The Cubis 2 is authorized the second version of Joyetech’s innovative tank that operated the market at the opening of last year. A modernized Cubis Pro was later released, but due to its performance issues, it never took off. This innovative version is still is a 22 mm tank with lid fill & top-fed airflow, & it’s still set up for low-wattage sub-coming & MTL vaping with greater resistance heads – but much of the rest has been changed from the first. Even the trademark coil head & chimney system is gone. Luckily, Joyetech kept the price low. It’s currently on pre-order at Heavengifts for only $16.90. Wow!

Joyetech Cubis 2 Intro

The Cubis 2 is an active 3.5 mL tank that tells me a bit of Smok Brit Beast with its low profile & coned drip tip (but the Cubis 2 tip allows 510 tips directly into it). Joyetech created this tank extra compressed at just 22 mm x 43 mm (including the tip), & it has a more finished appearance & idea than the original. The coil order has been redesigned, too, so it should vape differently. A coil threaded onto the base of the chimney is replaced by a more traditional head threaded to the bottom of the tank, but the heads are harmonious with the old method (though the old heads won’t work here). That’s great news for vapers that don’t want a new tank, or maybe just fancy the functionality of the primary Cubis.

The Cubis 2 has any new coil heads – the ProC-BF series – for various vaping styles. Coupled with the tank will be their new 0.6-ohm SS316 coil head for MTL vaping (though it seems a bit small of resistance for MTL). Other resistances prepared will be SS316 1.0-ohm, a new Clapton 1.5-ohm (both MTL), & a SS316 0.5-ohm coil head (for direct-lung). The TPD (ProC-BFL) coil heads are the same inside, but they’re made with more outside mass to overcome the juice function without increasing the tank size itself.

The Cubis 2 seems to be a new atomizer, not just an update to the previous model.

The originally slotted top fill is accessed via a three-stage child lock. You must rotate the (improved) air flow ring, start the top cap back, then flip open. It looks similar a lot compared to the original, but it shouldn’t be too bad concerning this tank is not a juice guzzler & wouldn’t need a lot of refills. I do get involved with adding another case of failure to the part of the atty that gets done so much. My guess – & hope – is it will be okay & Joyetech cruelty tested this “child lock.”

As a long time fan of Joyetech, I am curious to find out if the Cubis 2 will fulfill the promise of the original. The original Cubis had a lot going for it, at least plan wise. It was leak-proof, the coils were easy to swap out, & the capacity method was ingenious & simple – & up to that point, we hadn’t noticed anything like it. But with production issues, all that goes out the window. If these new coils are enduring without issues of spit back or flooding, this may be the tank that MTL vapers have been waiting for. What do you think? Let us know in the comments section.

Joye CuBox

The most important part of the CuBox is its lack of any significant display. Instead of any wattage & restraint readings, the minimalist screen features nothing more than a Joyetech logo, designating the mod is on, & a five-bar power meter. Though the CuBox has a 50-watt best output, there is no evidence of this anywhere on display, so users are going to have to trust the technology.

Features Joye CuBox:

2-5/8″ x 1-9/16″ x 15/16″ Dimensions

510 Contact Pin with Stainless Steel Threads

Simple One Button Design

Dual Circuit Protection

3000mAh Built-in Battery

50W Maximum Output

Micro USB Port for Charging

0.2ohm Minimum Resistance

Bottom Ventilation Holes

Top OLED Display

Maximum 2A Charging Current

That’s because the CuBox is a direct wattage device, with no improvement abilities. Instead, the mod detects the coil, & makes automatic adjustments for what it “feels” will be an optimal power level.

This is where I had my first query with the CuBox. Though I underst& Joyetech’s goal of starting vaping as simple & accessible as possible for newcomers, allowing them to only slap on a tank & vape up to 50 unregulated watts is irresponsible. Without understanding what the device is doing, or WHY it’s doing it might make it mild to puff away, but it does nothing to educate them on safe vaping practices.

Yes, I know companies have done related “auto detect” devices with much more power output, but those are aimed at experienced, high-wattage vapers. These users expected have the know-how to decipher when things are operating, & more importantly, when they aren’t. The CuBox is designed for ex-smokers & great new vapers, making the unregulated construction concerning, & potentially dangerous.

An All-Too-Real Safety Lesson

As mentioned earlier, I needed two CuBox kits to complete the study, because my original silver & black test model was faulty from the outset. Though I can’t be sure, I understand the essential collection was inadequate, causing the mod to exude an uncomfortable amount of heat after just a few seconds of firing on a full charge.

On top of this, the heat continued to pour from the venting for nearly an hour after practicing the CuBox. When it finally cooled to the touch, I realized it was because the battery had drained completely without implying used more than three draws. Mind you, the mod wasn’t FIRING, but the battery was somehow engaged.

I recharged using the included USB cable, which also produced a great number of heat – likely from the overpowered 2-amp quick charge feature. After nearly three hours, the indicators certainly showed full, & I tried again. This time, I managed to get five puffs before the mod once again became unbearable to hold. Additionally, the device was bootlegging out wattage well above the tank’s limitations, as I got nothing but hard hits before giving up entirely.

The replacement kit technically worked without overheating, reducing my attention a bit. But the included Cubis 2 tank endured a problem, & even the “working” device proved to barely function as needed.

An Odd Duck Tank, with a Confusing Purpose

The Cubis 2 is a different atomizer, to say the least. Though it was originally advertised as a tank that could hold all sorts of vapers, this is a strict mouth-to-lung device, with no viable use for any style beyond MTL.

With a 3.5mL capacity (2mL in the EU variant), & a child-proof locking top-cap with airflow control, the Cubis 2 certainly resembles like a new vape tank. But in use, this is a throwback of the highest order. Using tiny replacement coils, including TINIER juice stream flows, it’s much to use only high-PG liquids in the Cubis 2.

I’ve seen recommendations of 50/50 or smaller, but after getting blank but hard hits after just a few puffs, I was forced to dig deep in my e-liquid graveyard to find some “vintage” juice that could wick adequately. Doing so created for a more tolerable experience, but the razor-thin juice ports still had difficulty keeping up. & the seemingly different wattage output of the CuBox – often shifting puff to puff – only made the Cubis 2 perform more intermittently.

Even stranger is the addition of two PROC stainless steel replacement coils in the box, rather than using a canthal piece. Considering the CuBox is a straight-wattage device, why not utilize a coil that burns more constantly & consistently? Estimated at 0.6 ohms specific, the coils could probably handle greater wattage use, but the juice flow restriction ensured this would never happen.

Finally, the semi-wide bore drip tip is fixed, but there is a 510 adapter added in the box. However, using the adapter & a standard 510 made the tank oddly lanky, with subdued flavor as a result of the extended range between cap & coil.

When the Cubis 2 worked well, the flavor was strong & vapor was surprisingly good. But these consequences were all too rare. If you’re a converted smoker watching for a few stealth puffs from time to time, the Cubis 2 could be enough. In short, this is not a tank for steady vaping.

Back to the Box…

Joyetech CuBox Kit Review – Getting back to the start of this review, the CuBox determined to be just as tricky using tanks different than the Cubis 2. In fact, “unsteady” might be too generous. I had difficulty getting any consistent performance using other MTL & restricted lung devices, as if the device was having a hard time reading these different coils, & setting an appropriate output.

The effect was erratic puffs on even the most proven MTL atomizers, including stalwarts like the Kayfun Mini v3 & the Digiflavor Siren. The CuBox overwhelmed these RTAs at first, then seemingly backed itself down to the point where the vape was limp & benign.

Switching to older tanks like the old Kanger Subtank Mini with a new 0.5-ohm coil (yes, I still have a bunch of these lying around), the CuBox teased me with a few high draws that provided an ample amount of vapor. But this too was short-lived, & before long, the mod backed down to nearly no strength output at all.

I even went so far as to h& off experimenting to my wife, who just vapes mouth-to-lung. She was quickly thrown by the lack of control benefits, & didn’t fare much better than I did, though she did report better flavor than me, using her own Kayfun Mini v3.

It’s pretty obvious that Joyetech needed the CuBox paired with the Cubis 2 at every time, which is frustrating. But considering the strange heat bursts & battery draining concerns, it’s apparently safest for users to do just that. The only satisfying vape I got from the CuBox was with a distinct PROC coil. But again, these times were fleeting.

Complicated Kit, Simple Conclusion

Regarding the no-frills, non-adjustable design of the Joyetech CuBox, this kit should have been a boon for new vapers & these looking for an simple, stealthy vape. But there’s a fine line between lack of difficulty & lack of usability, & the CuBox obliterates it within nearly every use case.

When coupled with the lack of information & severe heat I received from my defective test model, the difficulties only mount for vape novices.

In the end, with a bafflingly erratic power output, unclear display, & the handcuff of essentially limiting users to one tank, Joyetech aimed for uniformity & ended up making something complex. Something so complex, that it’s completely unusable.

Tip for beginners: We firmly suggest 6mg e-liquid or lower with this atomizer. Sub-ohm atomizers produce higher throat hit than cheap & st&ard resistance atomizers. Using this atomizer with a nicotine level above 6mg will usually taste burnt or harsh.

Warning: This tank uses sub-ohm resistance coils. This tank should only be used by expert users. Extra safety precautions should be followed when using a sub ohm tank. This tank will only work on a mechanical mod or a regulated mod capable of firing sub ohm atomizers & coils. For example, if you have a 0.2ohm coil, your mod must be able to fire atomizers of 0.2ohm or lower. You must also assure that your batteries can h&le sub ohm atomizers & coils. If you’re using a regulated mod, make sure it can h&le the amps. Improper use can lead to injury or damage. For mechanical mod users, please use 20 Amp batteries or higher. Use the OHMS LAW CALCULATOR, CHECK YOUR AMPS, & be safe! Any questions, please contact us by email.

NOTE: Use special attention when working with Li-ion cells, they are very sensitive to charging characteristics & may explode or burn if mishandled. Make sure the user has enough knowledge of Li-Ion rechargeable batteries in charging, discharging & assembly before use. Always charge in/on a fire-proof surface. Never leave charging batteries ignored. We are not liable for loss if there is any modification of the batteries/chargers in any form or shape (including pack making).It is recommended using Lithium Ion rechargeable batteries with a control circuit (protection PCB) to assure safe charge, discharge, etc., use of lithium ion batteries without a protection circuit is potentially hazardous

PG

Acronym for Propylene Glycol. An ingredient found in most e-liquids. Generally speaking, the more PG in an e-liquid, the better the throat hit. It also makes e-liquids thinner.

Throat Hit

The slightly harsh, burning, tingling feeling at the back of your throat when vaping. Most vapers desire a decent throat hit because it emulates the effect of smoking cigarettes. Normally, the more nicotine an e-liquid contains, the stronger the throat hit.
